@Fluffy\(* ^ *)/ try hiding it in you hair or in your socks under your foot any place that the teacher can not touch or feel also look sick to make yourself feel innocent to why you came late

@SLEEPY4EVER And How do I use that cheat so that the teacher won't notice? Getting it out of my shoes is pretty difficult in class. And There's only one bathroom in there too.

@Fluffy\(* ^ *)/ just a bit kid glue paper on your bare chest or shirt

@Fluffy\(* ^ *)/  I wish you all the best 

@Fluffy\(* ^ *)/ do they make you remove your shoes too? If not, you you hide a chit in your shoes. Or just tuck it near you shoe laces, and even if they make you remove it, they won't find it. That, or you can it on the back of your neck with tape. Pretend you're scratching or rubbing your neck, and take the chit out. If they ask why you're touching your neck so much, just say it hurts a little from bad posture. No one will question it.

@Aizawa.mood That's actually quite useful!!

@Vernon Avaritt 3 Thank you!!

I can't say I recommend this but I suppose we've all been there...

get a pen where the ink can be removed - remove the ink and place a real thin piece of paper in there  (maybe a mechanical pencil, it's not weird to disassemble that and less likely for ink blotch stains). 

if your allowed gum and your careful unwrap the wrappers and scribble on the inside. Rewrap the candy so it looks untouched and place back in gum packet. Take a photo before unwrapping so you know how it meant to look. If the packet is wrapped in plastic then glad wrap and a hair dryer onto the plastic can make something look commercially rewrapped.

inside the lining of the pencil case. Or by sewing a brand label in on the inside you create a pocket for small paper. Aquire the brand fabric by cutting up another clothing item and undo the stitches using small scissors in the pencil case or a pencil sharper blade (this can be a bit difficult as you don't want to be wrestling with stitches in a pencil case in public) 

bandaid - those big square ones with padding. Place a little folded square of paper under that pad.  Teachers don't want to rip off your bandaids. To make it look extra convincing, dribble a little dark red on the Band-Aid and let it dry before putting it then maybe place it on the inner elbow, like you just had a blood test/ needles for a realistic placement. If you are struggling to discreetly take it off put your hand up and say your hands bleeding on the test paper can I go to the nurses office for a new Band-Aid. Long fluttery sleeves might give you better cover for peeling it off if it's on your hands.

allowed liquids? Get a wide dark water bottle with a fully removable lid. Scribble on the inside of the bottle then fill the bottle with a dark drink? Cordial? just make sure the ink is safe ingestable and doesn't run when wet. Guzzle the drink start of test then peer inside. 
this a bit common and teachers might look for it but most rectangular rubbers have a cardboard sleeve, scribble on the inside of that and redress the rubber.

wear watches? Write on the underside/skin side of the watch band. Start of the test take it off put it on the desk so it looks like your minding the time and observe your formulas. 
I've totally not tried these...

@Needtoread Those are alot of advices and none of them work for me😭
